The HYW4000P is a petrol-powered pressure washer powered by the 420cc 14hp, four-stroke Hyundai engine, which provides a maximum output of 4000psi, and a massive flow rate of 15 litres per minute, built for the toughest of cleaning tasks.

This petrol pressure washer model is favoured by cleaning professionals and used in industrial, agricultural and commercial environments. As the largest Hyundai petrol pressure washer, it's also portable and well balanced, mounted on a solid base with large puncture-proof foam filled tyres on single-piece wheels. Weighing 61kg, the HYW4000P is easy to transport from one job to the next, which is essential for professional cleaners.

The HYW4000P is fitted with the heavy-duty, Italian Annovi Reverberi (AR) RSV4G40 pump which is designed for constant hard work and reliable performance. It also features a thermal relief valve for regulating the temperature and preventing the Annovi Reverberi pump from overheating.

A 15 metre hose and lance, four nozzles and a turbo nozzle are included as standard and changing the attachments couldn’t be made easier due to the quick release fittings and connections. 

Suitable for gravity feed / mains supply. Water feed: Garden hose with Q/R connector. Must have sufficient volume to match the pump flow rate. Not supplied with suction kit, however it will draw from a barrel. It is recommended that the first time the pressure washer is used, it should be connected it to a mains supply to ensure all valves are free moving. After this it is fine to use with a water butt or drum.
